As millions of Americans hunker down to slow the spread of COVID-19, U.S. broadband networks are seeing a significant spike in usage. While industry insiders say that the U.S. internet should be able to handle the strain overall, broadband availability, affordability, and slow speeds could still pose a serious problem for many housebound U.S. residents. From a report: In a blog post, Cloudflare noted that Seattle, ground zero for the U.S. coronavirus spread, has seen internet usage spike by some 40 percent. Key internet exchanges in cities like Amsterdam, London, and Frankfurt have seen a 10 to 20 percent spike in traffic since around March 9. ISPs use a number of modern network technologies to handle congestion in real time, often letting them intelligently and automatically “deprioritize” the traffic of heavy users in overloaded areas. Even then, the massive surge in usage will likely impact U.S. broadband speeds in the weeks and months to come, industry trackers say. Broadband Now, a company that tracks U.S. broadband availability and speed, told Motherboard that six of the biggest U.S. cities by population have seen little to no change in median speed test results from the past 11 weeks.
